74300-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74300-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,0 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74300-22:
(7*7)+(6*4)+(5*3)+(4*0)+(3*0)+(2*2)+(1*2)=94
94 % 10 = 4
So 74300-22-4 is a valid CAS Registry Number.
